Abstract:
According to an aspect of the invention there is provided a water treatment system for treating water for use in a hydroponic plant cultivating system which includes a filter for filtering unwanted particles, an anti-scaling mechanism to inhibit scaling and precipitation of insoluble solids on the filter, a coagulator for coagulating at least minerals and heavy metals contained in the water, an oxidation-reduction controller for measuring and controlling oxidation-reduction potential of the water, a Ph controller for measuring and controlling the Ph value of the water, a carbon dioxide enriching apparatus for enriching the water with carbonic acid, a de-clustering mechanism for de-clustering water molecules of the water; and an aerator for increasing the level of dissolved oxygen in the water.
Abstract:
Methods, systems, and devices for water treatment or for preventing fouling of components of water treatment systems can include the upstream introduction of nanobubbles in-line and/or in close proximity to a reverse osmosis membrane in the water treatment system. The nanobubbles can bind to and cluster (flocculate) nanoparticles (and possible larger solid particles) so that they can be removed and not foul water purification components such as reverse osmosis membranes. The nanobubbles can also interact with and change some characteristics of nanoparticles and thereby reduce fouling of some system components, such as reverse osmosis membranes, or other components. The systems, methods, and devices disclosed herein can help produce potable water safe for human consumption in a more cost-effective manner, e.g., by reducing maintenance costs and in some cases manufacturing costs.

Abstract:
The present invention relates to a method of preparing and separating biopolymers and biopolymer fractions useful for wastewater treatment applications from sewage sludge comprising the steps of disrupting the bacterial cell walls of bacteria present in the sewage sludge by at least 75% to release the intracellular contents of the bacterial cells and separating the biopolymers from any contaminants present.
Abstract:
Le procédé selon l'invention pour le traitement de boues, en particulier de boues portuaires polluées, est caractérisé par le fait qu'il comprend les opérations consistant : - à mélanger lesdites boues avec des gravats de béton et/ou de pierres, - à traiter par broyage ledit mélange boues/gravats pour obtenir un broyat, et - à réaliser une opération de criblage dudit broyat, simultanément à un traitement de chauffage, pour obtenir au moins deux granulométries différentes de broyat. L'invention concerne également l'installation pour le traitement de gravats, en particulier de gravats mélangés à des boues, apte à mettre en œuvre le procédé précité, cette installation comprenant des moyens broyeurs (2), des moyens cribleurs (4) associés à des moyens de chauffage (5), et des moyens de transfert (3) entre les deux.
Abstract:
Die vorliegende Erfindung betrifft eine Aufbereitungsanlage sowie ein Verfahren zur Behandlung von Wasser in der Aufbereitungsanlage mit den Schritten: i) Einleiten (11) von zu behandelnden Wasser, in dem biologisch abbaubares Material von Mikroorganismen vorhanden sind in ein Belebungsbecken (10), das Teil der Aufbereitungsanlage ist; ii) Einleiten von Gas (13) in das Belebungsbecken (10) zur Behandlung des Wassers; und iii) Ausleiten (12) des behandelten Wassers aus dem Reaktionsraum (10). Das erfindungsgemäße Verfahren ist insbesondere dadurch gekennzeichnet, dass das eingeleitete Gas zumindest teilweise ionisiert ist, vorzugsweise mit einem Anteil von Ionen von höchstens 1*10 9 Ionen pro Gramm Trockensubstanz pro Stunde des biologisch abbaubaren Materials und der Mikroorganismen. Dadurch kann die Produktion von Blähschlamm erfolgreich reduziert oder verhindert werden.
